碩士 === 國立中正大學 === 電機工程研究所 === 99 === The objective of this thesis is to implement a tiled digital display system. This system expects to have no platform-specific and hardware-specific constraints, and is possible to operate well in all general-purposed PCs, laptops and handheld devices. It will also support all media formats of the MPEG system. Users can use several standalone machines to collaborate with each other to compose a digital display system. In which every machine just has the ability to play MPEG format media files, and it can range from handheld devices up to PCs. In the case of implementation techniques, this system provides a master clock server to provide an absolute time so that machines can synchronize to each other externally. Beside external synchronization, it also deals with the popular lip sync problems. In the case of software development cost, it is based on the free, cross platform and open-source projects. It is not only low-cost but also cross platform. The portability is also better.
